That order included instructions for Judge Duffin to dismiss the case. The one-page order was filed today, court records show.

The U.S. Supreme Court only takes a small percentage of the cases it is asked to review.

Dassey and his uncle, Steven Avery, were convicted of murdering the freelance photographer after she came to the Avery property to take pictures of a vehicle for an advertisement. Avery and Dassey are serving life prison terms.

Avery's most recent legal move was to appeal a Sheboygan County judge's ruling denying him a new trial to the state Court of Appeals.

Dassey and Avery's cases gained attention in 2015 after Netflix aired "Making a Murderer," which examined Halbach's death and spawned conjecture about Avery and Dassey's innocence. Authorities who worked on the cases said the series was biased.
